Abstract
Apparatus for sawing of curved-form timber feeds the log past a band saw such that the cut follows the curved form of the log. Spaced guides function to guide the log in a curved-form path through the saw. The guides are displaceable in a direction transversely to the feeding direction of the log depending on the curved form of the log. The guides may comprise guide rollers provided on each side of the log to be forced to the sides of the log.
